Kinetics of Nitrous Oxide Decomposition

Abstract

Abstract The decomposition of nitrous oxide has been studied in the temperature range 1815-3365K using a shock tube technique. Principal results of this study were the determination of the rate constants for the reactions and The experiments were conducted behind incident shock waves in mixtures of N2O and various diluent gases (Ar, Kr, N2, O2). Infrared emission from the 5.3 μm vibration-rotation band of NO and from the 4.5 μm vibration-rotation band of N2O was used to monitor the concentration-time profiles of NO and N2O. A computer simulation of the experiments was used to infer k1 and k2, with the following best-fit results: and for M = Ar, Kr, N2
